FILLING-END HOLDER' FOR WEFT-BEPLENISHING LOOMS.

Specification of LettersPate'nt. Application filed lamina-3728, 1908.Serial No. 413,120.

Patented Sept. 1,1908.

To all whom itmay concern:

Be it'known that L'Jomv (3. EDWARDS, a citizen of the United States, andresident of Brookline, county of Norfolk, State of Massachusetts, haveinvented an Improvement in Filling-End Holders for Weft-ReplenishingLooms, of which the following descri tion, in

connection with the accompanying rawing,

are transferred one byone to the shuttle, as in United States Patent No.529940 granted November 27, 1894- to J. H. Northrop.

The filling-ends are led from the ti S of the bobbins around the edge ofa bell ike disk and secured at their extremities by being woun'dwabout acentral knob-like end-holder,

and the accumulated waste filling must be ally by cutting it off with aknife. The mass ofwaste musty cutoff whether the endholderis' rigidlyand permanently attached to the filling-feeder or removable therefrom,asit is tightly wound upon the shank-0f the end-holder and clings firmlytoit.

I M present invention has for its-object the p d ction of an end-holderso constructed and arranged that the waste ma be readily removed orStripped without t e use of a,

knife or cutting instrument and with a minimum expenditure of time. I I

The novel features of my invention will be described in the subjoinedspecification an particularly-pointed out in the following ,li igure 1is a vertical section of the usual fee er, with one embodiment of mypresent invention applied thereto ,Fig. 2 is-a side ele- Yation ofthe'two-part fillin -end holder, detached, the parts of the ho dei'being sepa- -rated*;-Fig. 3 is a right hand end elevation of the part ofmember of the end-holder which Zia-permanently attached to thefilling-feeder; 4 is aviewsimilar to Fig.1 of a modified form of my,invention; Fig. 5 is aside elevation of the ermanently attached memberoi end-holder; Fig. 6. is a right-hand GlBVB:

4 of yet another modification to be described; Fig- 8 is a sectionalview of the removable member detached. I

Referring to Fig. 1 the stud 1 on which the filling-feederisrotatablyniounted, the, sur rounding sleeve 2 which connects the buttand tipsupportin plates of the feeder, (not shown), and the ell-likedisk 3 having its hub 4 attached by a set-screw 5 to the sleeve 2, areand may be all of usual construction in Northrop looms, the hub 4 havin"an outward extension 6, shown as slightFy and socketed at 7. U on thehub I mount the fillin -end holder, erein comprising an expansibl etubular member attached per manentlyto the 'hub, upon which member thefilling-ends are wound to hold them in place, and a manually detachableexpander adapted to normally expand and increase the diameter of'thetubular member. I

Referring to' Figs. 1, 2 and 3 the permanently attached member isshownas a longiconical tudinally slitted tube or barrel 8, made of Msheet-metal of suitable resilience or s ringiness', and shaped at itsinner end to orm a tapered base 9 which fits over the hub 6 and ispermanently secured-thereto, as by screws 10. The tubular art or barrel8 is preferably cylindrical w en in its "normaL-or 'unexpandedcondition, Fi 2, at the left, the I transversely Segmental ngers 8 whichform the barrel *receiving the extremities of the fill-in -ends, whichare woundabout the'barrel '.W en the latter is expanded.

The detachable member of the end-holder is shown as a ta cred shank 11having at its outer end an en ar ed head or knob 12, the inner end beingrec uced at 13, to enter the socket 7 of the hub 6. When the shank isushedinto place it spreads or expands the barrel 8, increasing itseffective diameter and givin it a conical shape, as SllOWIllIl Fig. 1,and the part 13 of the shank by seating in the I hub makes theend-holder rigid.-

The filling-ends are wound upon the expanded barrel, and when a mass ofwaste'has and should be removed the weaver grasps the head 12 andwithdraws the detachable member. Thereupon the springfingers 8 formingthe barrel contract and resume their natural position,- decreasing-thediameter of the barrel'so that the mass of waste 14 can-be a"iiqiithemef. Fig."7 is-a view similar to Fig. -slippediofi with aslight movement of the accumulated, as at 14, see dotted lines Fig. 1,

5 member unlocks it.

In the modification shown in-Figs. 4, 5.and 6 the base 17 of theerrpansible barrel 18 is non-continuous, exposing the hub 6 for aportion of its surface, and a radial hole is 20 made in the exposed partof the hub for a slidable locking pin 19, Fig. 4, pressed inward by alight spring 20,-.therounded inner end of the'pin enterin the socket 7vof the hub.

' The reduced en pandingmember has an annular groove 22 whichis enteredby the endof the pin when. said member is in its operative position,lockingit in place, as will The inward pushof the expanding member willcause the locking'devic e to -act automatically, and an outward pullwillrelease said member from control of the locking device when it-isdesired to strip off accumulated waste from the expansible member 18..

In Fig. 7 I have shown what is practically a reversal of the structuresshown in Figs. 1 *and 4, the expansible member 25 in this modificationbeing the removable member of the end-holder, said member being made asa longitudinally slotted tube, fastened at its outer end to a boss 26 onthe knob-like head 27, the boss having a central lug 28, Fig. 8. The hub6 has fixedly attached to it by a setscrew 29 thereduced end of anoutwardly end'to receive the lug 28, and near the hub the shankisrovided with an annular groove 31 into which snap the slightly inturnedfree ends 32 of the spring fingers forming the barrel 25. When theremovable, expansible member, shown separately in Fig. '8, is pushedontothe'shank 30 the barrel-25 is err panded, as shown in Fig. 7, theinturned ends .32 snapping into the groove 31 to lock the memberstogether. The fillin -ends are wrapped. around the expanded arrel, andwhen a mass of waste accumulates the removable member is detached by aquick-outward pull on the head 27, the barrel 25 0011-" it is drawn offthe shank, loosen-.

which can be easily tracting as g the hold of the waste, 1'

.1 t ipped off y the fingers. The lug 28 by entering the socket in theouter end of the shankiassists in providing a firng support fore:s1the.head,27.;

by making steady. outward pull on the head of the detachable.

of the shank 21 of the ex be clearly understood.

Y panding member,

tapered shank 30 having a socket in its outer It will be manifest thatby the use of invention no cutting of the waste is required .to removeit, for the qontraction of the expansible member upon removal of theexpanding member leaves the mass of waste loose upon the said expansiblemember, and

it' can be pushed or brushed ofi by a simple I sweep of thehand. v y

Modifications or changes in details of'con- 375 struction may 'be madeby those skilled in the art without departing from the splrit and scopeof my invention-as set; forth in. the appended claims.
